   3 # This script attempts to guess a canonical system name
   4 # similar to the output of config.sub.
   5 # If it succeeds, it prints the system name on stdout, and exits with 0.
   6 # Otherwise, it prints an error message on stderr, and exits with 1.

   8 # The plan is that this can be called by configure scripts if you don't
   9 # specify an explicit system type (host/target name).
  10 #
  11 # Only a few systems have been added to this list;
  12 # please add others (but try to keep the structure clean).
